Looking to identify Bosch accelerometers for data sheet

[jdessino]

Hi all! This is my first time posting to these boards.

My team is working on communicating with some OTS automotive impact sensors which have Bosch accelerometers inside them. We're looking to make the sensor available for the aftermarket, using the same exact Bosch IC (or an updated version of the same thing - it doesn't matter). But all of that is dependent on identifying the actual chips we have and getting the datasheet.

The package is soicw-16, but the markings haven't led us anywhere.

The chip markings are:

"01227"

"1703/01"

"N0751F0498"

We also decapsulated the IC to see if there were any part markings on the die. It looks like there are two dies inside. One has markings "CG968." The other has markings "CMB271."

I've uploaded some images of the package and die markings. Any help we could get in identifying these would be awesome!

Hello jdessino,

Actually on Bosch sensortec web site, we couldn't find you part, then we could provide any information about it. https://www.bosch-sensortec.com/products/motion-sensors/accelerometers/

You can contact your supplier to apply for the corresponding document you want to get.
